CHAPTER 26 INSTRUCTION SET
This chapter lists each instruction set of the 78K0/LC3 in table form. For details of each operation and operation
code, refer to the separate document 78K/0 Series Instructions User’s Manual (U12326E).
26.1 Conventions Used in Operation List
26.1.1 Operand identifiers and specification methods
Operands are written in the “Operand” column of each instruction in accordance with the specification method of
the instruction operand identifier (refer to the assembler specifications for details). When there are two or more
methods, select one of them. Uppercase letters and the symbols #, !, $ and [ ] are keywords and must be written as
they are. Each symbol has the following meaning.
• #: Immediate data specification
• !: Absolute address specification
• $: Relative address specification
• [ ]: Indirect address specification
In the case of immediate data, describe an appropriate numeric value or a label. When using a label, be sure to
write the #, !, $, and [ ] symbols.
For operand register identifiers r and rp, either function names (X, A, C, etc.) or absolute names (names in
parentheses in the table below, R0, R1, R2, etc.) can be used for specification.
